Nah it really doesn't come down to that at all.

If this rumor is to be believed it comes down to the following:

PS4 GDDR5 - able to push larger amounts of data at once, but much slower cycle rate

360 DDR3 - able to push less data at once but do it more rapidly + having more memory to work with.

PS4 - .50 caliber machine gun firing 5 rounds per second

360 - .30 caliber machine gun firing 10 rounds per second and having more ammo to fire with.

 

I really don't know how else I can illustrate this to people...GDDR5 doesn't necessarily mean faster performance. Infact for non GPU tasks its much worse.

I think you need a little more about the GDDR5 tech... it is not like GDDR4 or GDDR3... more for graphcis... GDDR5 was created for both worlds and more... graphcis and computer.

I did my reaserach on GDDR5. GDDR5 = DDR3 where the memory bandwidth is pretty much doubled and clock speed is higher...however latency is a lot higher as well. 

If GDDR5 was good for general computing, it would be used by motherboards. Its only good for graphics which have to spit out large quantities of data at once.

Like I said, GDDR5 as GPU memory in PS4 = amazing. GDDR5 as unified architecture shared by GPU and CPU = not amazing at all.

Ideally next gen consoles would have dedicated GDDR5 for video and dedicated DDR3 for CPU.
